Closed-cycle CO2 cars might be a reality one day

Do you hate the idea of your car spewing exhaust? There might be a way to stop it without using any expensive batteries or hydrogen fuel cells. According to the New York Times, a pair of scientists at Los Alamos National Laboratory (LANL) are working on a way to trap exhaust fumes (by blowing them over a liquid solution that contains potassium carbonate) and recycle the trapped carbon into either methanol, gasoline or jet fuel. F. Jeffrey Martin and William L. Kubic Jr. have named their process Green Freedom and a press release by the LANL says the recycling could be done on cars or planes. The fuel generation doesn't take place on board - the carbon needs to be brought to a facility where the CO2 would be turned into the fuel - and the carbon transformation process is itself energy-intensive. Kubic and Martin are working on a way to streamline this step of the dream (possibly using nuclear reactors), but they're not there yet. Oh, and what is the dream? Recycled gasoline that costs $1.40 a gallon to make. Can't hate that.
